Perceptions of Cognitive Load and Workload in Nurse Handoffs: A Comparative Study Across Differing Patient-Nurse Ratios and Acuity Levels.

Medical errors, often resulting from miscommunication and cognitive lapses during handoffs, account for numerous preventable deaths and patient harm annually. This research examined nurses' perceived workload and cognitive load during handoffs on hospital units with varying patient acuity levels and patient-nurse ratios. Conducted at a southeastern US medical facility, the study analyzed 20 handoff dyads using the National Aeronautics and Space Administration Task Load Index to measure perceived workload and cognitive load. Linear regressions revealed significant associations between patient acuity levels, patient-nurse ratios, and National Aeronautics and Space Administration Task Load Index subscales, specifically mental demand (P = .007) and performance (P = .008). Fisher exact test and Wilcoxon rank sum test showed no significant associations between these factors and nurses' roles (P > .05). The findings highlight the need for targeted interventions to manage workload and cognitive load, emphasizing standardized handoff protocols and technological aids. The study underscores the variability in perceived workload and cognitive load among nurses across different units. Medical-surgical units showed higher cognitive load, indicating the need for improved workload management strategies. Despite limitations, including the single-center design and small sample size, the study provides valuable insights for enhancing handoff communications and reducing medical errors.

“Should you really chat while reading?” effects of on-screen multitasking and text disfluency on integrated understanding

Students' multitasking during lectures or academic assignments is a common activity that may have negative effects on performance. It is therefore relevant to investigate under what conditions such negative effects can be reduced. The current study brought together two separate lines of research to examine the effects of on-screen multitasking and text disfluency. Multitasking required students to read and respond to social media messages during reading. Text disfluency was perceptual in the form of harder-to-read versus easy-to-read text. We included 208 university students, who were randomly assigned to one of the four conditions resulting from a 2 x 2 between-subjects design. Participants read two dual-positional texts on sun exposure and health. Dependent on the assigned condition, they could read perceptually fluent or disfluent texts, and they could intermittently receive, or not receive, on-screen social media messages while reading. As outcome variables, we measured participants’ perception of cognitive load, integrated text understanding, and metacognitive calibration of text understanding. We also controlled the possible contributions of the individual differences of prior knowledge, reading comprehension skills, working memory, and cognitive flexibility. Results showed a negative effect of multitasking on the integrated understanding of the dual positional texts with non-multitaskers outperforming multitaskers. Perception of cognitive load and metacognitive calibration were not affected by multitasking. No impact of disfluency was observed for any of the outcome variables, and the interactive effect of multitasking and disfluency was also not statistically significant. Limitations and directions for future research are discussed.

Augmented Reality in Natural Sciences and Biology Teaching: Systematic Literature Review and Meta-Analysis

This article presents the results of a systematic literature review followed by a meta-analysis of studies on the use of Augmented Reality (AR) in the teaching and learning of Natural Sciences and Biology, among primary and secondary school students. The variables considered were the effects on student learning and motivation, as well as other variables like students understanding and students’ perception of the cognitive load. The teaching contexts and strategies used in association with AR were also considered. The PRISMA methodology was used in articles published between 2010 and 2023, in EBSCO, Science Direct, Scopus, Springer Link, Taylor & Francis and Web of Science databases. Seven hundred and twenty-one articles (721) were found, which, after applying the inclusion and exclusion criteria, were reduced to 15. The results showed that, in most studies, AR associated with certain teaching strategies and using a quasi-experimental research methodology produced better results in learning and student motivation and other variables such as student understanding and memorization (from Bloom's taxonomy), and perception of cognitive load. The overall analysis of the data allowed us to observe a strong effect size value (d = 1.13 [0.39;1.86]) in favour of the experimental group regarding learning and a moderate effect on motivation when using AR (d = 0.52 [0.30;0.74]). The same occurred with other variables studied where students obtained better results, which translated into a small or medium effect size. For example, in the perception of cognitive load, the effect size was d= 0.73. Doi: 10.28991/ESJ-2024-08-04-025 Full Text: PDF

Understanding assessment tasks: Learners’ and teachers’ perceptions of cognitive load of integrated speaking tasks for TBLT implementation

TBLTis an educational approach to L2 learning and teaching where tasks constitute the main focus of classroom instruction. In its implementation, one of the major challenges facing teachers is the lack of empirical evidence for task design and selection relating to task complexity and the cognitive load imposed by tasks perceived by learners. To address the issue, we investigated EFL learners' and teachers' perceptions of cognitive load of integrated speaking tasks, one type of advocated tasks for TBLT, and factors that affect such perceptions within Robinson's Triadic Componential Framework as proposed by some scholars in the task research field. In a mixed-methods design, we collected data using a self-rating scale, a self-rating questionnaire and semi-structured interviews in the context of integrated speaking tasks for helping shed light on task design and selection criteria. Our analysis revealed that task complexity factors contributed to participants' perceptions of cognitive load, and in the four factors under investigation, prior knowledge was perceived as a stronger determinant of cognitive load than planning time, steps involved and task type. These findings provide empirical evidence for task design and selection in TBLT implementation, especially for the use of integrated speaking tasks in TBLT aiming at EFL speaking instruction. They also provide implications for L2 assessment.

Students’ Perception of Cognitive Load in an Accelerated DPT Program with a Blended Curriculum

Administrators and educators in higher education are interested in how academic tutoring services and gender impact perceptions of cognitive load and, therefore, students’ academic success. However, a lack of evidence existed in the literature regarding physical therapy students’ perception of cognitive load in an accelerated Doctor of Physical Therapy program with blended learning. Participants in this quantitative, non-experimental study completed the adapted Cognitive Load Scale to indicate their perception of cognitive load, participation in academic tutoring services, gender, and age. The DPT students perceived high cognitive overload, but a t value of 0.37 and a p value of 0.71 indicated that their perception was not significantly related to gender. Further, a t value of -3.09 and a p value of 0.005 indicated that academic tutoring services played a vital role in minimizing the perception of cognitive overload. However, the p value of 0.11 of the parametric multiple linear regression analysis and the p value of 0.59 of the interaction term indicated no moderating relationship between academic tutoring services and gender. This evidence may assist physical therapy administrators and educators of DPT students in re-structuring blended learning programs and accelerated curricula to reduce student perceptions of cognitive overload.

The quizzing effect depends on hope of success and can be optimized by cognitive load-based adaptation

It is well established that quizzing fosters learning. However, some gaps in the literature relating to the fit of quizzing to learner characteristics and learner perceptions during quizzing still need to be addressed. The present study focuses on two of these aspects: achievement motives and perceptions of cognitive load. First, quizzing entails that learners' performance is judged against some standard of excellence. This might make it appealing and effective for learners with high hope of success and low fear of failure in particular. Second, it is an open question whether providing quiz questions that are adapted to learners’ perceived level of cognitive load during quizzing would be beneficial. To address these questions, we randomly assigned learners to either non-adaptive quizzing, adaptive quizzing, or note-taking. We found that quizzing benefits concerning learning outcomes were moderated by hope of success. Furthermore, the adaptation via cognitive load ratings substantially increased the quizzing effect.

The effects of time-compressed instruction and redundancy on learning and learners’ perceptions of cognitive load

Can increasing the speed of audio narration in multimedia instruction decrease training time and still maintain learning? The purpose of this study was to examine the effects of time-compressed instruction and redundancy on learning and learners' perceptions of cognitive load. 154 university students were placed into conditions that consisted of time-compression (0%, 25%, or 50%) and redundancy (redundant text and narration or narration only). Participants were presented with multimedia instruction on the human heart and its parts then given factual and problem solving knowledge tests, a cognitive load measure, and a review behavior (back and replay buttons) measure. Results of the study indicated that participants who were presented 0% and 25% compression obtained similar scores on both the factual and problem solving measures. Additionally, they indicated similar levels of cognitive load. Participants who were presented redundant instruction were not able to perform as well as participants presented non-redundant instruction.

The effects of diagrams and time-compressed instruction on learning and learners’ perceptions of cognitive load

The purpose of this study was to examine the effects of diagrams and time-compressed instruction on learning and learners’ perceptions of cognitive load. The following design factors, visuals (visuals and non-visuals) and time-compressed instruction (0%-normal paced, 25, and 50%) were presented to 216 university students to analyze learning in a multimedia environment. Participants listened to audio instruction of the heart and those in the visuals condition viewed 19 diagrams that corresponded to the verbal instruction. The dependent variables consisted of four achievement tests: drawing, identification, terminology, and comprehension. Review behaviors (back and replay buttons) and learners’ perceptions of cognitive load served as additional dependent variables. The results of this study indicate that listening to normal or moderately compressed (25%) instruction in a multimedia environment supports learning. At these speeds, cognitive load is not increased thus allowing learners to gain a conceptual understanding of the material.

Effects of Online Reading on Popular Science Comprehension

The present study examines the effects of print and online presentations of a multiple document report on reader’s comprehension, perception of cognitive load, satisfaction, and attention. We hypothesized that users of online media would show poorer results compared with print users. An experimental protocol was used to assess readers’performance using print and online versions of a popular science magazine report. Hypertext led to higher perceived cognitive load and poorer comprehension of the complementary documents. The results suggest that presenting graphics in long hypertexts increases effort and reduces text legibility. The present data offer support for theories of disorientation and cognitive load in hypermedia learning.
